TL;DR: Homegrown IAM systems still work for login and token issuance, but Ory argues they have become identity debt as modern applications, API-first architectures, and machine and AI identities demand governed identity signals, scalable access control, and safer reuse across teams. The structural problem is that access can persist while understanding, governance, and compliance context fragment.
Editorial analysis by NHI Mgmt Group, based on content published by Ory: “Why It’s Time to Move Beyond Homegrown IAM”.
Key questions
Q: When does homegrown IAM become identity debt rather than a cost-saving choice?
A: Homegrown IAM becomes identity debt when the system still authenticates users but no longer supports governed reuse of identity data across the organisation.
Q: Why do custom IAM systems create risk when teams start reusing identity data?
A: Custom IAM creates risk because reused identity data often loses the policy context, ownership, and consistency it had at the source.
Q: What are the signs that identity governance is failing outside the core IAM stack?
A: Look for systems with no named owner, access lists that are updated by hand, accounts that survive after departures, and departmental tools that never appear in recertification reports.
Practitioner guidance
- Map identity debt across downstream consumers Identify where identity data is being exported, duplicated, or manually transformed for analytics, operations, and compliance use cases.
- Separate access control from identity governance Document which parts of the current stack only authenticate and authorise, versus which parts produce governed identity signals for other teams.
- Inventory machine and automated identity use cases Check whether service accounts, workloads, or AI-driven workflows are forced through human-centric auth patterns that were never designed for them.
Bottom line: Homegrown IAM can remain operational while still becoming a governance liability, because access success does not guarantee identity understanding or reuse.

Identity debt is what happens when access works but governance fragments. Homegrown IAM often survives because its core login path still functions, yet that does not mean the identity programme is healthy. Once identity data is copied into analytics pipelines, downstream applications, and manual exports, the organisation loses a single governed view of who or what is entitled to act. The practitioner implication is that functional authentication can conceal structural governance decay.
A question worth separating out:
A: They should test whether the platform can connect authentication, entitlement, and behaviour data across users, service accounts, tokens, and certificates. Coverage matters less than operational reach, so ask whether it can drive ownership, rotation, and response from one control plane instead of separate tools. That is the real indicator of programme maturity.
